hey gurus

I want to connect my existing phone to my asterisk server. im looking to build a very minimal server and I am limited in ports on my mobo. My little understanding leads me to believe that I need a fxs card to connect to my server. First question is if my previous statement is correct. If so, other than PCI, does anyone know if a low cost option I could use to connect to my server; for example, are there small form factor usb options or maybe motherboard with this port built in.

Any help on this topic is much appreciated.
thanks
